  The present invention relates to a continuous steaming / cooling device, a continuous steaming device, and a bar cleaning device for a bar conveyor used in a continuous cooling device for processing raw materials such as potatoes and vegetables.

  In general, continuous steaming and cooling devices, continuous steaming devices, and continuous cooling devices are used as devices for continuously cooking or cooling raw materials such as potatoes and vegetables, and they are equipped with a bar conveyor as a means for transporting raw materials. Yes. Since the transport surface of the bar conveyor has a plurality of bars connected with a gap, the transport surface has higher strength than a perforated belt or net conveyor, and the raw material is not easily clogged. In order to prevent the rolling of the raw material due to the impact at the time of raw material supply and the inclination of the conveying surface in the steaming device or the cooling device, the bar is partially used in addition to the round bar.

  For example, Patent Document 1 discloses a continuous steaming / cooling device capable of continuously steaming and cooling a raw material loaded on a conveying surface of a bar conveyor. In the continuous steaming cooling device, the steaming mechanism and the cooling mechanism are connected, the steaming mechanism has a plurality of steaming chambers partitioned by a plurality of partition plates, and the cooling device has an air cooling duct. Further, it is described that a water washing device 23 is provided downstream of the cooling device to continuously expose the bar to water during operation (Patent Document 1, page 6, lines 3 to 4 and FIG. 1).

Japanese Utility Model Publication No. 62-30600

  Raw material residue or boiled juice adheres to the bar of the bar conveyor of the continuous steaming and cooling device during steaming or cooling. By repeating the cooking or cooling, the deposits derived from the raw material are burnt or dried and firmly adhere to each other, so that there is a problem that the deposits are difficult to remove after washing after the operation.

  In the above-mentioned Patent Document 1, water is washed by a water washing device 23 on a running bar conveyor. However, simply applying water does not remove the deposits derived from the raw material, and it remains and adheres. The present invention is to solve the conventional problems as described above, and to provide a bar cleaning device for a bar conveyor that removes deposits derived from raw materials on the bar of the bar conveyor during operation so as not to stick.

  Hereinafter, the bar washing | cleaning apparatus 3 of the bar conveyor 2 which concerns on one Embodiment of this invention is demonstrated, referring drawings. For example, as shown in FIG. 1, the present invention is applied to a continuous steaming / cooling device 1 having a bar conveyor 2. In the continuous steaming / cooling device 1, a steaming mechanism 11 and a cooling mechanism 12 are connected. The raw material is input from the raw material supply port 13 and loaded on the bar 211 of the bar conveyor 2, proceeds in the direction of arrow a, is steamed and cooled by the steaming mechanism 11 and the cooling mechanism 12, and is discharged from the material discharge port 14.

  After discharging the raw material, the bar 211 is immersed by the immersion mechanism 4 of the bar cleaning device 3. The bar 211 is cleaned by rubbing with the brush 541 by the cleaning mechanism 5 of the bar cleaning device 3, returns to the position of the raw material supply port 13, and rotates to the steaming mechanism 11 again.

  The steaming mechanism 11 is located downstream of the raw material supply port 13, and a steaming chamber 111 is provided so as to surround the bar 211. Steam is supplied from the steam supply source 112 to the cooking chamber 111, and the raw material loaded on the bar 211 is continuously cooked.

  The cooling mechanism 12 is located downstream of the steaming mechanism 11, and a wind tunnel 121 is provided below the bar 211 of the bar conveyor 2. The raw material loaded on the bar 211 is continuously cooled as the air on the bar 211 is sucked into the wind tunnel 121.

  For convenience of explanation, FIG. 2 shows a part of the motor base 221 and the base 15, the wind tunnel 121, and the cleaning liquid supply path 42. FIG. 3 shows one of the base 15, the side plate 23, the support 218, the receiving roller 215, and the cleaning liquid supply path 42. Some or all of them are omitted.

  As shown in FIG. 2, the bar conveyor 2 includes a bar 211, a rotating part 21, a driving part 22, a side plate 23, and a pressing part 24. The rotating unit 21 includes a plate 212, an endless chain 213, a sprocket 214, a receiving roller 215, a rotating shaft 216, and a bearing 217. The drive unit 22 includes a motor base 221, a drive motor 222, a drive sprocket 224, a driven sprocket 226, and an endless chain 225. The drive unit may be a power transmission unit using a gear or a power transmission unit combining a belt and a pulley. The side plate 23 is fixed to the gantry 15 (not shown). The side plate may be omitted if the raw material does not roll off. The pressing portion 24 includes a rotating shaft 241, a bearing 242, and a pressing roller 243.

  Both ends of the bar 211 are fixed to the endless chain 213 via the plate 212, and the endless chain 213 is looped around the sprocket 214. The sprocket 214 is supported by a rotating shaft 216 together with the receiving roller 215, and the rotating shaft 216 is fixed to the mount 15 by a bearing 217. The bar 211 can be rotated without bending or overlapping if the receiving roller 215 is provided in a portion where the traveling direction of the bar 211 changes. Further, the rotating shaft 216 has a driven sprocket 226 of the drive unit 22 attached to one end.

  As shown in FIG. 3, a motor base 221 is fixed to the upper part of the gantry 15, and a drive motor 222 is installed thereon. As shown in FIG. 2, the drive motor 222 has a drive sprocket 224 attached to a rotary shaft 223, and an endless chain 225 is wound between the drive sprocket 224 and the driven sprocket 226. According to this configuration, the drive of the drive motor 222 is transmitted from the drive sprocket 224 to the driven sprocket 226 via the endless chain 225, and the sprocket 214 rotates. Then, the bar 211 rotates together with the endless chain 213. It is preferable to use a plurality of driving sprockets 224 and driven sprockets 226 in consideration of driving loads.

  If the bar 211 is long or has a large amount of raw material and the center part of the bar 211 bends and curves during transportation, the bar 211 can be supported by installing a plurality of support bodies 218 on the lower side and supporting them. 211 can be transported horizontally. The support 218 supports the bar 211 by fixing the support base 219 to the mount 15 (not shown). Furthermore, if the support body 218 is installed at a predetermined interval with respect to the bar 211, the level on the transport surface can be kept wide.

  As shown in FIG. 3, the bar 211 of the bar conveyor 2 moves downward after passing the drive unit 22, is pressed by the pressing roller 243 of the pressing unit 24, and is rotated to the dipping mechanism 4 of the bar cleaning device 3. . The traveling direction of the bar 211 in FIG. 3 is the arrow a direction. The pressing roller 243 is pivotally supported on the rotating shaft 241, and the bearing 242 of the rotating shaft 241 is fixed to the gantry 15. By installing the pressing roller 243, the traveling direction of the bar 211 can be changed or the bar 211 can be stretched.

  The dipping mechanism 4 of the bar cleaning device 3 includes a storage tank 41 that is immersed in a cleaning liquid that stores the bar 211 of the bar conveyor 2 bent downward, and a cleaning liquid supply path 42 that supplies the cleaning liquid to the storage tank 41. ing. The bar 211 of the bar conveyor 2 can be easily immersed by being bent to the lower part, and the influence of expansion and contraction due to steaming or cooling can be suppressed. As shown in FIG. 2 and FIG. 3, the storage tank 41 has a size that allows the bar 211 to be immersed therein, as long as the drain port 43 is provided, and the shape is not particularly limited. The storage tank 41 can be easily drained if the bottom surface is tapered toward the drain port 43 provided at the bottom. In addition, the storage tank 41 can be easily moved if it has a caster 44 at the bottom. Furthermore, the storage tank 41 can be easily cleaned as long as one surface can be opened.

  Examples of the cleaning liquid stored in the storage tank 41 include liquids such as water and alcohol, and solutions mixed with cleaning components such as surfactants. Since the temperature of the cleaning liquid is not particularly limited, the temperature may be increased by steam, steam drain, heater or the like. Further, gas may be supplied to the cleaning liquid in the storage tank 41 and bubbled. As shown in FIG. 3, the cleaning liquid supply port 45 is preferably installed above the storage tank so that it does not come into contact when the storage tank 41 moves. Thus, since the bar 211 is immersed in the cleaning liquid in the storage tank 41, the deposits on the bar 211 swell and become easy to peel off.

  For convenience of explanation, in FIG. 4 and FIG. 5, a part or all of the cooling mechanism 12, the pipe 561 of the injection unit 56, and the mount 15 are omitted as appropriate. The cleaning mechanism 5 of the bar cleaning device 3 is provided downstream of the immersion mechanism 4. As shown in FIG. 4, the cleaning mechanism 5 is divided into an upper cleaning mechanism 51 and a lower cleaning mechanism 52 with a bar 211 of the bar conveyor 2 interposed therebetween, and each includes a motor base 53, a rotating unit 54, a moving unit 55, and an injection unit 56. It is composed of The rotating unit 54 and the moving unit 55 are provided on the motor base 53, and the injection unit 56 is fixed to the gantry 15 at both ends. It is preferable to provide both the upper cleaning mechanism 51 and the lower cleaning mechanism 52 because the entire surface of the bar 211 can be cleaned.

  Hereinafter, the upper cleaning mechanism 51 will be described as an example. The rotating unit 54 includes a brush 541, a fixture 542, a rotating shaft 543, and a rotating motor 544. As shown in FIG. 5, in the rotation unit 54, the rotation motor 544 is fixed to the motor base 53, and a brush 541 is fixed to a rotation shaft 543 that penetrates the motor base 53. Then, the brush 541 is rotated by driving the rotation motor 544.

  The brush 541 arranges the rotation shaft 543 in parallel with the traveling direction (arrow a direction) of the bar conveyor 2. Here, “parallel” includes an inclination of around 15 degrees. Even if the bar 211 is long, the brush 541 with the short rotation shaft 543 can be used for moving cleaning, so that there is no risk of the rotation shaft 543 being bent, and the bristles of the brush 541 can be uniformly applied to the bar 211. When a roll brush is used as the brush 541, the adhering matter can be scraped off by the bristles of the brush 541 by rotation, so that the cleaning efficiency is good. Furthermore, if a plurality of roll brushes are connected as the brush 541 and fixed with the fixing tool 542, only the brush 541 that has been worn out by removing the fixing tool 542 can be replaced, and maintenance costs can be reduced.

  The moving unit 55 includes a guide 551, a traveling rail 552, a traveling tooth 553, a gear 554, an upper roller 555, a lower roller 556, a moving motor 557, and a rotating shaft 558. As shown in FIG. 4, in the moving unit 55, the traveling teeth 553 are provided on the lower surface of the traveling rail 552 arranged in a direction orthogonal to the traveling direction of the bar conveyor 2. As shown in FIG. 5, the moving motor 557 is fixed to the motor base 53, and a gear 554 is connected to a rotating shaft 558 passing through the motor base 53. Then, the gear 554 is rotated by driving the moving motor 557. As shown in FIG. 4, a guide 551, which will be described later, is fixed to the motor base 53 and is movably gripped on the traveling rail 552. Therefore, the brush 541 moves horizontally with the bar 211 along the running teeth 553 by the rotation of the gear 554. By moving the brush 541 in a direction perpendicular to the traveling direction of the bar 211, the entire brush side of the bar 211 can be rubbed, and the deposits derived from the raw material can be removed.

  For convenience, the upper roller 555 and the lower roller 556 are omitted in FIG. The guide 551 includes a slide guide 5511, a sliding plate 5512, and a pressing plate 5513. The slide guide 5511 is disposed so as to surround the traveling rail 552. The sliding plate 5512 is bent upward along the side surface of the slide guide 5511 and fixed to the slide guide 5511 so as to be sandwiched between the upper surface of the traveling rail 552 and the surface of the slide guide 5511. The pressing plate 5513 presses one surface of the slide guide 5511 and is fixed to the motor base 53 with a bolt or the like. The slide guide 5511 may be divided in consideration of maintainability, or may be formed of a wear-resistant resin. The sliding plate 5512 may be made of a material having good wear resistance and bending workability. The driving of the moving unit 55 is not limited to gear driving, and may be chain driving or cylinder driving.

  As shown in FIGS. 4 and 7, if the upper roller 555 and the lower roller 556 are provided on the motor base 53 and the upper and lower surfaces of the running rail 552 are rolled, the brush 541 can be moved smoothly. The numbers of the upper roller 555 and the lower roller 556 are appropriately determined depending on the size of the motor base 53 and the like.

  As shown in FIG. 7, the traveling rail 552 is provided with proximity sensors 57 on both side surfaces. When the proximity sensor 57 detects the holding plate 5513 of the guide 551, the brush 541 moves to one end on the opposite side due to the reverse rotation of the moving motor 557. The sensor is not limited to the proximity sensor 57, and may be a contact type, a photoelectric type, a laser type, or an ultrasonic type. Further, the detection target of the sensor is not limited to the pressing plate 5513, but may be any component that moves the cleaning mechanism 5.

  As shown in FIG. 4, the injection unit 56 includes a pipe 561 and both ends fixed to the gantry 15 and an injection port. The shape and material of the pipe 561 and the injection port are not particularly limited. The pipe 561 may be a tube or a hose in addition to a metal or synthetic resin pipe, and the nozzle may be a nozzle having a hole in the pipe 561 or a nozzle connected to the pipe 561. If the spray port sprays liquid, gas, or gas-liquid mixture toward the brush 541 or the bar 211 as the brush spray port 562, the cleaning property of the bar 211 is improved. In addition, as shown in FIG. 5, it is preferable to provide the traveling rail injection port 563 to inject the liquid toward the traveling rail 552, because the traveling rail 552 is more slippery.

  Further, the ejecting unit 56 may be provided at a position for ejecting the liquid, gas, or gas-liquid mixture to the bar 211 after passing through the brush 541. When the propellant is a liquid, the solution containing a solvent such as water or alcohol is assumed to be air, nitrogen, carbon dioxide, ozone, steam or the like. The gas-liquid mixture is a mixture of the liquid and gas.

  The distance between the dipping mechanism 4 and the cleaning mechanism 5 should be as short as possible so that the cleaning liquid attached to the bar 211 does not dry in the dipping mechanism 4. The configuration of the lower cleaning mechanism 52 is the same as that of the upper cleaning mechanism 51, and the positions of the brush 541 and the motor are not particularly limited. Further, the moving direction and moving speed of the upper cleaning mechanism 51 and the lower cleaning mechanism 52 and the positional relationship between them are not particularly limited.

  As described above, in the bar cleaning device 3 of the bar conveyor 2, the bar 211 is immersed in the cleaning liquid in the storage tank 41 and then rubbed with the brush 541. It can be cleaned efficiently without being stuck.
